1.Saving energy is so inportant in modern world. First of all, for a country, energy storage is an important standard to measure the strength of a country. Country's normal operation is dependent on energy.In addition, the basic life of each family needs energy to protect.At my house, we use the energy in the kitchen—for cooking and keeping food cold in the refrigerator. Those appliances are the largest in the house, and we eat food every day. At my partner’s house, the air conditioner uses the most energy. The most important is the world is hungry for energy, so we are more due to the save energy.And save energy can save our climte and environment.

2.When we burn fuel for energy, it sends pollution into the atmosphere, and over time, it is changing Earths climate. On the other hand, using cleaner, renewable forms of energy reduces those negative effects on the environment.

3.I think small individual projects are the better way to developrenewable energy sources because when local people care about a project, and they can understand exactly how much they are helping the environment as well as their own situation, they are more likely to support the project.

I think large government projects are the better way to develop renewable energy sources because governments have much better resourcesmoney, researchers, and engineersthan local individuals have. Governments can apply all of those resources to renewable energy projects, and they can accomplish more.
